Prior to reading your thread I did virtually the same thing
1. Downloaded the ipa
2. Changed it to a rar file
3. Deleted the map within the rar file "Payload\garmin-nav.app\storage-usa\.System"
4. Changed it back to a ipa file
5. use free iFunBox.exe to send it to the iPhone (Installous download folder)
6. Installed the app through the iPhone (Installous download folder)
7. Ran the app for a few seconds
8. Shut down the app
9. use free iFunBox.exe to send the new files to the iPhone "var\mobile\Applications\[APP DIR]\garmin-nav.app\storage-usa\.System"
10. use free iFunBox.exe to add following line to the hosts file in /etc
Typed this Line in /etc/hosts file:
127.0.0.1 [Only registered and activated users can see links. ] gold.garmin.com bronze.garmin.com

3D buildings layer will work, you must just edit the file settings_defaults.plist under garmin-nav.app folder.
Just look for <key>three_d_building</key> and change this from <false/> to <true/>. After that 3D buildings layer is already enabled by default and you can see 3D buildings on the map. Only you can't switch this layer off anymore, you need again to edit settings_defaults.plist file.
